and IState of Rhode Island, have invented.

. certain new and useful Improvements' .in

Loom-Pickers, of which the following isa specification.

This invention relates to improvements in loom-pickers', and has forits objects economy of construction and quickness in setting.

Iny all loom-pickers known to me there is a want of'simplicity in the construction, which adds an element to the ,cost which it is desirable to eliminate. Furthermore, by doing away with the set-screw arrangement for clamping the head upon the staf;l the clamping operation is more quickly performed.

n the drawings which illustrate my invention, Figure 1 is a side elevation showing my picker-head mounted on a picker-staff. Fig. 2 is a section corresponding to line 2 2 of Fig. 1. Fig. 3 is a section corresponding to line 3 3 of Fig. 2. Figs. 4 and. 5 are views of detached parts. Fig. 6 is a development of metal shell. Fig. 7 is a rear view of shell in its folded position.

1 is the picker-staff, and 2 the picker-shell. Picker-shell 2 is formed from a single piece of sheet metal and consists of the head 3, sides 4 5, side folders 6 6 7 7, and tailpieees 8 S, so

eut as to bend into a shape suitable for clamping on staff 1.

The head 3 is provided with a hole 20 to receive the point of the shuttle, and within the shell between the hole and the staff 1 are layers of leather or other suitable material adapted to serve as a buffer. The head 3 of the shell is parallel to the pickenstaff, thus making it possible to use leather pieces which are each of uniform thickness, and the.

inclosure formed by the sides 4 5 6 6 7 7 is of uniform Width at front and back, so that a leather piece 21 Iat the back will fit precisely into the place of the leather piece 21 next the head or in any intermediate position. This makes it possible to shift the leathers gradually forward, inserting new ones at the back as the forward ones become worn. Thegside fold portions 6 6 7 7 bend over the top'fand bottom o f the inolosure, holding the leathers, as clearly shown in Fig., 7. Not being fastened or otherwise tied together they are sure and permitting'easy remya able.

The reason for this peculf' 'iar shape'is to enable me to providetheflat locking-surface 17 Without having asofcalled high point at either side of same',; Vthus l giving a continually-increasing pressurey as 8,0' the locking device is turned into looked osition. It is noticeable also that this s` a e/ j makes it necessary to always turn in t e same direction when locking, which .is desirv18 is a perforation for the insertion cfa` turning-bar for locking the picker upon the staff 1. A bar can be permanently mounted inhole18,ifsodesired;butprefernottodoso. 'f In Figs. 1, 2, 3 I have shown an additional 9o or supplemental locking means consisting of a spring-pressed pi'n 19, which enters ldepression 12 onthe thrust-block 9 when' in locked position lbut this can be omittedg i without departing from thespirit of my ini" '95- vention. y

Ears 14 14 are adapted to-v enter the large. end of openings 15 15 and can then be moved to position in a Well-known manner, the tailpieces 8 A8 having suficierit flexibility to '10o permit them to enter.- When the tailpieces are thus spread apart, the entire,headhin'-A closure eX ands, the two sides separat" .ari fand 6.

I therefore call,'thelyfead-exfrs ' ,elosnre being separable sidewise to expand theflnclosure, and means to hold the shell hold lthe 'shell upon a stall.
